11 / 104 page ![]() Dual-Core Intel® Xeon® Processor 5000 Series Datasheet 11 Introduction 1.1 Terminology A ‘#’ symbol after a signal name refers to an active low signal, indicating a signal is in the asserted state when driven to a low level. For example, when RESET# is low, a reset has been requested. Conversely, when NMI is high, a nonmaskable interrupt has occurred. In the case of signals where the name does not imply an active state but describes part of a binary sequence (such as address or data), the ‘#’ symbol implies that the signal is inverted. For example, D[3:0] = ‘HLHL’ refers to a hex ‘A’, and D[3:0]# = ‘LHLH’ also refers to a hex ‘A’ (H= High logic level, L= Low logic level). Commonly used terms are explained here for clarification: • Dual-Core Intel® Xeon® Processor 5000 Series – Processor in the FC-LGA6 package with two physical processor cores. Dual-Core Intel Xeon processor 5000 series refers to the “Full Power” Dual-Core Intel Xeon Processor 5000 series with 1066 MHz Front Side Bus. For this document, “processor” is used as the generic term for the “Dual-Core Intel® Xeon® Processor 5000 series”. • Dual-Core Intel® Xeon® Processor 5063 (MV) – This is a lower power version of the Dual-Core Intel Xeon Processor 5000 series. Dual-Core Intel Xeon Processor 5063 (MV) refers to the “Mid Power” Dual-Core Intel Xeon Processor 5000 series. Unless otherwise noted, the terms “Dual-Core Intel Xeon 5000 series” and “processor” also refer to the “Dual-Core Intel Xeon Processor 5063”. • FC-LGA6 (Flip Chip Land Grid Array) Package – The Dual-Core Intel Xeon Processor 5000 series package is a Land Grid Array, consisting of a processor core mounted on a pinless substrate with 771 lands, and includes an integrated heat spreader (IHS). • FSB (Front Side Bus) – The electrical interface that connects the processor to the chipset. Also referred to as the processor front side bus or the front side bus. All memory and I/O transactions as well as interrupt messages pass between the processor and chipset over the FSB. • Functional Operation – Refers to the normal operating conditions in which all processor specifications, including DC, AC, FSB, signal quality, mechanical and thermal are satisfied. • Storage Conditions – Refers to a non-operational state. The processor may be installed in a platform, in a tray, or loose. Processors may be sealed in packaging or exposed to free air. Under these conditions, processor lands should not be connected to any supply voltages, have any I/Os biased or receive any clocks. Upon exposure to “free air” (that is, unsealed packaging or a device removed from packaging material) the processor must be handled in accordance with moisture sensitivity labeling (MSL) as indicated on the packaging material. • Priority Agent – The priority agent is the host bridge to the processor and is typically known as the chipset. • Symmetric Agent – A symmetric agent is a processor which shares the same I/O subsystem and memory array, and runs the same operating system as another processor in a system. Systems using symmetric agents are known as Symmetric Multiprocessing (SMP) systems. • Integrated Heat Spreader (IHS) – A component of the processor package used to enhance the thermal performance of the package. Component thermal solutions interface with the processor at the IHS surface. • Enhanced Intel SpeedStep Technology – The next generation implementation of Intel SpeedStep technology which extends power management capabilities of servers and workstations. |
